Purpose: To study indicators of central and peripheral hemodynamics in pregnant women with obesity of varying severity at a gestational age of 36-38 weeks. Materials and Methods: To study hemodynamic parameters (heart rate, SDD, UI, SI, OPSS, CR, LVMI) in pregnant women with obesity of varying severity, 127 pregnant women (I, main group) aged from 23 to 34 years were selected obesity of varying severity with gestational age 36-38 weeks. The second (control) group consisted of 28 pregnant women of the same age and gestational age with normal body weight (body mass index from 19 to 24.9 kg / m2). The groups were identical in age, gestational age, which allowed for an objective and comparative assessment. Results: At a gestational age of 36-38 weeks, hemodynamic parameters in women with normal body weight (BMI - 19-24.9 kg / m2) corresponded to the standards characteristic of healthy pregnant women of this gestational age. All women had an eukinetic type of blood circulation, RR was 1.15 ± 0.03 conventional units, LVMI - 0.59 ± 0.005 W × m2. RR corresponded to 18.4 ± 1.3 per minute, SpO2 - 97.7 ± 0.58%, hourly urine output - 0.80 ± 0.12 ml / kg / h, which indicates effective oxygenation and a completely satisfactory state of peripheral circulation , renal excretory function. An increase in BMI to 40 or more kg / m2 (morbid obesity of the III degree) contributed to the progression of signs of heart failure, which manifested itself in a significant decrease in one-time and minute cardiac output, CR, LVMI; increased heart rate; increased myocardial oxygen demand; decrease in hourly urine output. There was a hypokinetic circulation. Against this background, severe tachycardia was observed (heart rate - 93.7 ± 2.8 per minute). SDI and UPVS increased relative to the group of pregnant women with normal weight, respectively by 28.7% and 91.7%. DP was 14.5 ± 0.12 conventional units, which indicates a high myocardial oxygen demand. There was tachypnea (RR - 25.8 ± 0.2 per minute) and low blood oxygen saturation (SpO2 - 92.6 ± 0.6%). Conclusion: An increase in body mass index to 40 or more kg / m2 contributes to the progression of signs of heart failure, which requires an individual approach to prenatal preparation, the choice of timing, method of delivery and the method of anesthesia.
